'McDonaldization' of frogs
Frog fungus hammering biodiversity of communities

Everyone knows that frogs are in trouble. But a recent analysis by Washington University in St. Louis researchers of data on Central American frogs collected by a University of Maryland colleague shows the situation is worse than had been thought. Under pressure from an invasive fungus, the frogs in this biodiversity hot spot are undergoing "a vast homogenization" that is leaving behind simpler communities that increasingly resemble one another. "We're witnessing the McDonaldization of the frog communities," comments Kevin G. Smith, Ph.D., the lead author of the analysis and associate director of Washington University's Tyson Research Center, a site the fungus has also reached.

'Big Ideas'
What everyone should know about Earth sciences summarized in free NSF-funded e-booklet
June 5,
2009 --
If you're clueless about petrology, paleobiology and plate tectonics, the National Science Foundation and the Earth Science Literacy Initiative (ESLI) have just released a free pamphlet offering a concise primer on what all Americans should know about the Earth sciences. "The Earth Science Literacy framework document of 'Big Ideas' and supporting concepts was a community effort representing the current state-of-the-art research in Earth sciences," said Michael E. Wysession, Ph.D., chair of ESLI and associate professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis.

An opening ceremony for what could be one of North America's greenest buildings — a flagship building on the cutting edge of sustainable design and energy efficiency — was held May 29 at Washington University in St. Louis' new Living Learning Center at the university's Tyson Research Center. The Living Learning Center is a 2,900-square-foot facility built to meet the Living Building Challenge — designed to be the most stringent green building rating system in the world — of the Cascadia Region Green Building Council (CRGBC). No building has met its standard yet, but the Living Learning Center is in the running to be the first in North America.

An opening ceremony for what could be one of North America's greenest buildings — a flagship building on the cutting edge of sustainable design and energy efficiency — will take place at 4 p.m. May 29 at Washington University in St. Louis' new Living Learning Center at the university's Tyson Research Center. The Living Learning Center is a 2,900-square-foot facility built to meet the Living Building Challenge — designed to be the most stringent green building rating system in the world — of the Cascadia Region Green Building Council (CRGBC).

'Biodiversity beyond the habitat's borders'
Plant biodiversity enhanced thanks to spillover from landscape corridors

Researchers at Washington University in St. Louis, along with collaborators at three other universities, have discovered that the biodiversity in a patch of habitat can extend outside the borders of a protected area; this effect is magnified when corridors — skinny strips of land — connect the habitats. Their findings, reported in this week's online issue of the Proceedings of the National Academy of Sciences, provide a strategy for managing nature preserves to maximize biodiversity in the small spaces that are already formally protected.

Novel energy
DOE makes largest research award in Danforth Campus history
April 28,
2009 -- Washington University and the Donald Danforth Plant Science Center have received two awards totaling $35 million from the U.S. Department of Energy (DOE) to do research on novel energy initiatives. At $20 million, the Washington University research award is the largest ever received on the Danforth Campus. The $15 million for the Donald Danforth Plant Science Center is the largest the organization has ever received.

'Taco shell' protein
Orientation of middle man in photosynthetic bacteria described
April 13,
2009 --
Researchers at Washington University in St. Louis have figured out the orientation of a protein in the antenna complex to its neighboring membrane in a photosynthetic bacterium, a key find in the process of energy transfer in photosynthesis. Robert Blankenship, Ph.D., Markey Distinguished Professor of Biology and Chemistry in Arts & Sciences, led a team that for the first time combined chemical labeling with mass spectroscopy to verify the orientation. The team also included Michael Gross, Ph.D., WUSTL Professor of Chemistry, Immunology and Medicine, and Chemistry graduate students Jianzhong Wen and Hao Zhang. A paper describing this work appeared recently in the Proceedings of the National Academy of Sciences USA.

'Ecomorality' and religious naturalism
Biologist discusses sacred nature of sustainability
Feb. 16,
2009 --
The hot topics of global warming and environmental sustainability are concerns that fit neatly within the precepts of religious naturalism, according to Ursula Goodenough, Ph.D., professor of biology in Arts & Sciences at Washington University in St. Louis. In addition to being a renowned cell biologist, Goodenough is a religious naturalist and the author of The Sacred Depths of Nature, a bestselling book on religious naturalism that was published in 1998. Religious naturalism neither requires belief in God nor excludes such faith. Rather, the movement is based on what Goodenough describes as "an exploration of the religious potential of nature."

Discovery could lead to better rice yields
Technology identified could reduce the spread of rice virus

Building on plant virus research started more than 20 years ago, a biologist at Washington University in St. Louis and his colleague at the Donald Danforth Plant Science Center in St. Louis have discovered a technology that reduces infection by the virus that causes Rice Tungro Disease, a serious limiting factor for rice production in Asia.
